<p>A packet data division retransmitting method is provided to improve packet data transmission efficiency by optimizing a structure of a RLC(Radio Link Control) PDU(Protocol Data Unit) segment divided for the retransmission. A protocol data unit segment structure includes a sequence number field(804), a segment Indicator field(806), a sub sequence number field, and a data field(810). The sequence number field grapes the sequence of PDU generated in a radio link control layer. The segment indicator field indicates information to segment PDU in a retransmission process. The sub sequence number field grasps the sequence of the PDU segment. The data field is composed of a part of one or more service data unit delivered from an upper layer.</p> |
